| Posted: 13 Feb 2014 11:23 AM PST When individuals from different groups interbreed, their offspring's DNA becomes a mixture of the DNA from each admixing group. Pieces of this DNA are then passed along through subsequent generations, carrying on all the way to the present day. Researchers have now produced a global map detailing the genetic histories of 95 different populations across the world, spanning the last four millennia.  |
| Ancient reptile birth preserved in fossil: Ichthyosaur fossil may show oldest live reptilian birth Posted: 12 Feb 2014 03:37 PM PST Ichthyosaurs were giant marine reptiles that evolved from land reptiles and moved to the water. Scientists report a new fossil specimen that belongs to Chaohusaurus (Reptilia, Ichthyopterygia), the oldest of Mesozoic marine reptiles that lived approximately 248 million years ago. The partial skeleton was recovered in China and may show a live birth.  |
| No such thing as porn 'addiction,' researchers say Posted: 12 Feb 2014 12:32 PM PST Journalists and psychologists are quick to describe someone as being a porn "addict," yet there's no strong scientific research that shows such addictions actually exists. So says a clinical psychologist in practice in a large behavioral health program.  |
| Well-child visits linked to more than 700,000 subsequent flu-like illnesses Posted: 12 Feb 2014 11:46 AM PST New research shows that well-child doctor appointments for annual exams and vaccinations are associated with an increased risk of flu-like illnesses in children and family members within two weeks of the visit. This risk translates to more than 700,000 potentially avoidable illnesses each year, costing more than $490 million annually.  |
| Solving an evolutionary puzzle: Atlantic killifish thriving in highly polluted water Posted: 12 Feb 2014 11:46 AM PST For four decades, waste from nearby manufacturing plants flowed into the waters of New Bedford Harbor -- an 18,000-acre estuary and busy seaport. The harbor, which is contaminated with polychlorinated biphenyls (PCBs) and heavy metals, is one of the EPA's largest Superfund cleanup sites. It's also the site of an evolutionary puzzle that researchers have been working to solve.  |
| Plastic shopping bags make a fine diesel fuel Posted: 12 Feb 2014 10:28 AM PST Plastic shopping bags, an abundant source of litter on land and at sea, can be converted into diesel, natural gas and other useful petroleum products, researchers report. The conversion produces significantly more energy than it requires and results in transportation fuels -- diesel, for example -- that can be blended with existing ultra-low-sulfur diesels and biodiesels.  |
| Posted: 12 Feb 2014 10:28 AM PST We are all aware of the health benefits of dietary fiber. But what is dietary fiber and how do we metabolize it? Researchers begun to uncover how our gut bacteria metabolize the complex dietary carbohydrates found in fruits and vegetables. Trillions of bacteria live in human intestines -- there are about ten times more bacterial cells in the average person's body than human ones. Known as "microbiota," these bacteria have a vital role to play in human health: they are central to our metabolism and well-being.  |
| The physics of curly hair: Researchers develop first detailed model for a 3-D strand of curly hair Posted: 12 Feb 2014 10:28 AM PST The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they're often similar in their hair, which is usually extremely rigid or -- if it moves at all -- is straight and swings to and fro. It's rare to see an animated character with bouncy, curly hair, since computer animators don't have a simple mathematical means for describing it. But now, researchers have developed the first detailed model for a 3-D strand of curly hair.  |
| New pathway for fear discovered deep within brain Posted: 12 Feb 2014 10:28 AM PST Fear is primal. In the wild, it serves as a protective mechanism, but for humans, fear is more complex. A normal amount keeps us safe. But too much fear, like PTSD, can prevent people from living healthy lives. Researchers are working to understand how the brain translates fear into action. Today, scientists announce the discovery of a new neural circuit that links the site of fear memory with a brain area that controls behavior.  |
| Jaw dropping: Scientists reveal how vertebrates came to have a face Posted: 12 Feb 2014 10:27 AM PST Scientists present new fossil evidence for the origin of one of the most important and emotionally significant parts of our anatomy: the face. Scientists show how a series of fossils, with a 410 million year old armored fish called Romundina at its center, documents the step-by-step assembly of the face during the evolutionary transition from jawless to jawed vertebrates.  |
| Eat spinach or eggs for faster reflexes: Tyrosine helps you stop faster Posted: 11 Feb 2014 05:38 AM PST A child suddenly runs out into the road. Brake!! A driver who has recently eaten spinach or eggs will stop faster, thanks to the amino acid tyrosine found in these and other food products.  |
| Majority of Americans have their heart health facts wrong Posted: 07 Feb 2014 07:23 AM PST Despite the fact that heart disease is the leading cause of death for both men and women in the U.S., about three-quarters (74 percent) of Americans do not fear dying from it, according to a recent survey.  |
| Posted: 07 Feb 2014 06:40 AM PST Researchers have conceptualized a novel strategy to efficiently harness low frequency vibrations as infinite power source for miniature electronic devices.  |
| Dating refined for Atapuerca site where Homo antecessor appeared Posted: 07 Feb 2014 05:37 AM PST One of the issues of the Atapuerca sites that generates the most scientific debate is the dating of the strata where the fossils are found. A study has clarified that the sediment of Gran Dolina, where the first remains of Homo antecessor were discovered in 1994, is 900,000 years old. The findings at the Lower Palaeolithic cave site of Gran Dolina, in the Sierra de Atapuerca mountain range (Burgos), have led to major advancements in our knowledge of human evolution and occupation of Eurasia.  |

| MLB largely responsible for players' steroid abuse, researcher says Posted: 14 Feb 2014 05:39 PM PST The widespread use of illegal steroids among Major League Baseball players has been fueled by an "economy of bodily management," the free agent market and exploding television revenues, a labor and disability historian argues in a newly published research paper.  |
| Mars rover heads uphill after solving 'doughnut' riddle Posted: 14 Feb 2014 11:40 AM PST Researchers have determined the now-infamous Martian rock resembling a jelly doughnut, dubbed Pinnacle Island, is a piece of a larger rock broken and moved by the wheel of NASA's Mars Exploration Rover Opportunity in early January.  |
| Geographic variation of human gut microbes tied to obesity Posted: 14 Feb 2014 10:09 AM PST Researchers know that obese people have a different balance of microbes in their guts: more Firmicutes, fewer Bacteroidetes. Now researchers have found that people living in northern latitudes have a greater proportion of the Firmicutes associated with obesity than do people living farther south, and a smaller proportion of Bacteroidetes. The implications are unclear, though microbes may evolve with people to better extract energy from food in colder climates.  |
| Brain's 'sweet spot' for love found in neurological patient Posted: 14 Feb 2014 06:20 AM PST A region deep inside the brain controls how quickly people make decisions about love, according to new research. The finding, made in an examination of a 48-year-old man who suffered a stroke, provides the first causal clinical evidence that an area of the brain called the anterior insula "plays an instrumental role in love," said neuroscientist Stephanie Cacioppo, lead author of the study.  |
| Cat parasite found in western Arctic Beluga deemed infectious Posted: 13 Feb 2014 12:35 PM PST Scientists have found for the first time an infectious form of the cat parasite Toxoplasma gondii in western Arctic Beluga, prompting a health advisory to the Inuit people who eat whale meat.  |
| Crazy ants dominate fire ants by neutralizing their venom Posted: 13 Feb 2014 11:22 AM PST Invasive "crazy ants" are rapidly displacing fire ants in areas across the southeastern US by secreting a compound that neutralizes fire ant venom, according to a new study. It's the first known example of an insect with the ability to detoxify another insect's venom.  |
| Robotic construction crew needs no foreman Posted: 13 Feb 2014 11:21 AM PST On the plains of Namibia, millions of tiny termites are building a mound of soil—an 8-foot-tall "lung" for their underground nest. During a year of construction, many termites will live and die, wind and rain will erode the structure, and yet the colony's life-sustaining project will continue. Inspired by the termites' resilience and collective intelligence, a team of computer scientists and engineers has created an autonomous robotic construction crew. The system needs no supervisor, no eye in the sky, and no communication: just simple robots—any number of robots—that cooperate by modifying their environment.  |
| Call to scientists: Stop excluding left-handed people from scientific studies Posted: 13 Feb 2014 08:26 AM PST Left-handed people really do have different brains and genes from right-handed people. Yet left-handed people are almost never included as study subjects in scientific research. Therefore in a new article, a call is launched for more research into left-handed people.  |
| Posted: 13 Feb 2014 06:51 AM PST Scientist finds historical evidence of biological weapons research in Nazi Germany. Researchers came to the conclusion that, although a major entomological institute was established to combat insect-borne diseases such as typhoid, it also carried out research into whether mosquitoes -- which host malaria -- could be used in biological warfare.  |
| Human earwax: Overlooked source of personal information? Posted: 12 Feb 2014 08:21 AM PST Scientists have used analytical organic chemistry to identify the presence of odor-producing chemical compounds in human earwax. Further, the amounts of these compounds differ between individuals of East Asian origin and Caucasians. The findings suggest that human earwax could be an overlooked source of personal information.  |
| Black raspberry candies find the sweet spot for cancer prevention study Posted: 12 Feb 2014 06:31 AM PST Scientists engineer the first berry-based chemopreventive confections that can withstand the rigors of a large-scale clinical trial. An ongoing prostate cancer study is trying to determine if the medical edibles can improve post-surgery outcomes  |
| Australian state has higher rate of hypothermia deaths than Sweden Posted: 12 Feb 2014 06:31 AM PST New research shows that the state of South Australia has a higher rate of deaths from extreme cold compared with the northern European nation of Sweden.  |
| Oregano oil: Could pizza herb prevent winter vomiting disease? Posted: 11 Feb 2014 06:12 PM PST Scientists have found that carvacrol -- the substance in oregano oil that gives the pizza herb its distinctive warm, aromatic smell and flavor -- is effective against norovirus, causing the breakdown of the virus' tough outer coat.  |
| Are you a high achiever? Even the best products might leave you dissatisfied Posted: 11 Feb 2014 08:37 AM PST Make the honor roll, go for the promotion, or try the tastiest entrée on the menu. In almost every facet of our culture, we are told to "go for the gold." So, why settle for "good enough" when "something better" is within reach? According to a new study, constantly striving for the best may be magnifying negative feelings like regret and dissatisfaction in other parts of our daily lives.  |
| Dressing down: Can this actually boost your social status? Posted: 11 Feb 2014 06:42 AM PST From wearing a suit to a wedding to donning a tie for a job interview, American society has established unspoken rules for dress codes and proper etiquette. But there's always that one guy who wears the bright socks or the obnoxious bow tie. According to a new study, this type of behavior has the potential to increase a person's perceived success.  |
| Silicone ear is 'indistinguishable' from real thing for man who lost ear to cancer Posted: 10 Feb 2014 11:18 AM PST After losing an ear to cancer, a patient received a silicone ear that looks remarkably real. A surgeon implanted three small metal posts in the side of the patient's head. Each post is fitted with a magnet. The prosthetic ear also is magnetized, so it sticks to the metal posts.  |

| Children living close to fast food outlets more likely to be overweight Posted: 13 Feb 2014 07:04 PM PST Research shows that children living close to fast food outlets are more likely to be overweight. Researchers looked at weight data from more than a million children and compared it with the availability of unhealthy food from outlets including fish and chip shops, burger bars, pizza places, and sweet shops. It is hoped that the findings will help shape planning policy to help tackle childhood obesity.  |
| 'Sexy' underwear is not the only way to feel feminine on Valentine's Day Posted: 13 Feb 2014 07:03 PM PST TV makeover shows and glossy magazines can leave women feeling guilty for not wearing "sexy" lingerie -- especially on Valentine's Day.  |
| Scientists find cell fate switch that decides liver, or pancreas? Posted: 13 Feb 2014 12:35 PM PST Stem cell scientists have a new theory for how stem cells decide whether to become liver or pancreatic cells during development. A cell's fate, the researchers found, is determined by the nearby presence of prostaglandin E2, a messenger molecule best known for its role in inflammation and pain. The discovery could potentially make liver and pancreas cells easier to generate both in the lab and for future cell therapies.  |
| Cat parasite found in western Arctic Beluga deemed infectious Posted: 13 Feb 2014 12:35 PM PST Scientists have found for the first time an infectious form of the cat parasite Toxoplasma gondii in western Arctic Beluga, prompting a health advisory to the Inuit people who eat whale meat.  |
| Embryology: Scientists crack open 'black box' of development and see a 'rosette' Posted: 13 Feb 2014 11:23 AM PST We know much about how embryos develop, but one key stage -- implantation -- has remained a mystery. Now, scientists have discovered a way to study and film this 'black box' of development. This new method revealed that on its way from ball to cup, the blastocyst becomes a 'rosette' of wedge-shaped cells, a structure never before seen by scientists.  |
| Posted: 13 Feb 2014 11:23 AM PST When individuals from different groups interbreed, their offspring's DNA becomes a mixture of the DNA from each admixing group. Pieces of this DNA are then passed along through subsequent generations, carrying on all the way to the present day. Researchers have now produced a global map detailing the genetic histories of 95 different populations across the world, spanning the last four millennia.  |
| Psychologist shows why talking to kids really matters Posted: 13 Feb 2014 11:22 AM PST Exposure to child-directed speech sharpens infants' language processing skills and can predict future success. New work indicates early intervention can improve language skills in kids lagging behind.  |
| Posted: 13 Feb 2014 11:22 AM PST Researchers have tied a particular gene to the development of cortical convolutions -- the prominent but enigmatic folds covering the surface of the human brain. Their discovery should shed some light on these characteristic contours, which have been the subject of wild speculation for ages, and perhaps also provide a better understanding of how such brain ridges form, how they evolved from our pre-human ancestors and, ultimately, how they influence brain function.  |
| Air pollution increases risk for hypertension in pregnant women Posted: 13 Feb 2014 09:24 AM PST Breathing the air outside their homes may be just as toxic to pregnant women -- if not more so -- as breathing in cigarette smoke, increasing a mom-to-be's risk of developing deadly complications such as preeclampsia, according to findings from a new study.  |
| Two new weapons in the battle against bacteria Posted: 13 Feb 2014 09:24 AM PST Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists have discovered two hitherto unknown mechanisms of action that can be used to permanently disarm an important bacterial protease.  |
| Posted: 13 Feb 2014 09:24 AM PST Every day our cells take in nutrients from food and convert them into the building blocks that make life possible. However, it has been challenging to pinpoint exactly how a single nutrient or vitamin changes gene expression and physiology. Scientists have now developed a novel interspecies model system that allows these questions to be answered.  |
| Is zinc the missing link for osteoarthritis therapies? Posted: 13 Feb 2014 09:23 AM PST A study reveals that osteoarthritis-related tissue damage is caused by a molecular pathway that is involved in regulating and responding to zinc levels inside of cartilage cells. A protein called ZIP8 transports zinc inside these cells, setting off a cascade of molecular events that result in the destruction of cartilage tissue in mice. The findings could lead to a new generation of therapies for osteoarthritis.  |
| New stem cell method may eliminate need for blood donations to maintain platelet supply Posted: 13 Feb 2014 09:23 AM PST Platelets, whose primary function is to prevent bleeding, are vital for treating various forms of trauma and blood diseases. However, they can only be obtained through blood donations at present. Researchers recently found a way to create platelets without the need for donated blood, an advance that could possibly erase supply shortages and ensure platelet treatments for all who need them.  |
| Posted: 13 Feb 2014 09:16 AM PST Upconversion nanoparticles -- new types of luminescent nanomaterials that release high-energy photons after laser light stimulation -- can penetrate deeper into tissue and are more photochemically stable than conventional bioimaging agents, such as quantum dots and organic dyes. Luminescent nanocrystals doped or impregnated with small amounts of rare-earth ytterbium (Yb) ions are particularly effective at photon upconversion. The specific lasers used to excite Yb dopants, however, can also heat water molecules in biological samples causing cell death or tissue damage.  |
| Breast cancer survivors reap benefits of weight training, study finds Posted: 13 Feb 2014 08:26 AM PST Researchers are working with breast cancer survivors to help them regain muscle mass and bone density lost through both chemotherapy and the aging process.  |
| Posted: 13 Feb 2014 08:26 AM PST In the first study of its kind, a consortium of physicians found that giving stroke patients intravenous magnesium within an hour of symptom onset does not improve stroke outcomes, according to research.  |
| Understanding basic biology of bipolar disorder Posted: 13 Feb 2014 06:50 AM PST Instead of only using a standard clinical interview to determine whether individuals met the criteria for a clinical diagnosis of bipolar disorder, researchers combined the results from brain imaging, cognitive testing, and an array of temperament and behavior measures. Using the new method, they and their collaborators have identified about 50 brain and behavioral measures that are both under strong genetic control and associated with bipolar disorder. Their discoveries could be a major step toward identifying the specific genes that contribute to the illness.  |
| Sedation before nerve block increases risk, not pain relief, research suggests Posted: 13 Feb 2014 06:43 AM PST New research suggests that sedating patients before a nerve block needed to diagnose or treat chronic pain increases costs, risks and unnecessary surgeries, and sedation does nothing to increase patient satisfaction or long-term pain control.  |
| Metal implants may cut chemotherapy side effects, study suggests Posted: 13 Feb 2014 06:43 AM PST Cancer patients could one day experience fewer side effects from chemotherapy following a discovery that opens the door for more targeted treatments. Researchers have identified a possible way of treating tumors that would see doctors place harmless metal implants at the cancer site.  |
| Metabolic syndrome similar in different age groups, study shows Posted: 13 Feb 2014 05:37 AM PST Metabolic risk factors cluster similarly in children and adults, according to a study. Furthermore, in adults, the clustering of these risk factors increases the risk of premature death caused by type 2 diabetes, myocardial infarction and cardiovascular diseases. The results indicate that lifestyle interventions aiming at the prevention of type 2 diabetes and cardiovascular diseases should be invested in already in childhood.  |
| Could restless sleep cause widespread pain in older people? Posted: 13 Feb 2014 05:37 AM PST Researchers in the U.K. report that non-restorative sleep is the strongest, independent predictor of widespread pain onset among adults over the age of 50. According to the study anxiety, memory impairment, and poor physical health among older adults may also increase the risk of developing widespread pain. Muscle, bone and nerve (musculoskeletal) pain is more prevalent as people age, with up to 80% of people 65 years of age and older experiencing daily pain. Widespread pain that affects multiple areas of the body —- the hallmark feature of fibromyalgia —- affects 15% of women and 10% of men over age 50 according to previous studies.  |
| Could obstacles to lethal injection lead to an end to the death penalty? Posted: 13 Feb 2014 05:34 AM PST Access to required anesthetic agents for a lethal injection is quickly disappearing, leaving the future of the death penalty in the United States in question. "Because the European Union opposes the death penalty, it prohibits the export of goods for executions [and] requires a time-consuming preauthorization review for every shipment of a potential 'dual use' pharmaceutical," says a biomedical ethics expert and professor of law and medicine.  |
| ADHD drugs not linked to increased stroke risk among children Posted: 12 Feb 2014 03:36 PM PST Children who take medication to treat attention deficit hyperactivity disorder don't appear to be at increased stroke risk, according to a study.  |
| Sleep apnea common among stroke-related brainstem injuries Posted: 12 Feb 2014 03:36 PM PST People whose brainstems are affected by their stroke have a significantly higher prevalence of sleep apnea than those who have stroke-related injury elsewhere in the brain, according to new research. Sleep apnea is marked by interrupted breathing during sleep and can lead to serious health problems including heart disease and stroke.  |
| Two Parents with Alzheimer's Disease? Disease May Show up Decades Early on Brain Scans Posted: 12 Feb 2014 01:43 PM PST People who are dementia-free but have two parents with Alzheimer's disease may show signs of the disease on brain scans decades before symptoms appear, according to a new study.  |
| Article addresses report on genome-based therapeutics, companion diagnostics Posted: 12 Feb 2014 12:32 PM PST The promise of personalized medicine is the ability to tailor therapy to the patient's genome and their cancer's genome using a series of tests, but the system guiding the development of those tests is complex, and plagued with challenges.  |
| Train like an Olympian: Six things we can learn from elite athletes Posted: 12 Feb 2014 11:45 AM PST Everyone should have the experience of training for and accomplishing a physical goal, says a physical therapy professor.  |
| Test for persistent Lyme infection using live ticks shown safe in clinical study Posted: 12 Feb 2014 10:29 AM PST In a first-of-its-kind study for Lyme disease, researchers have used live, disease-free ticks to see if Lyme disease bacteria can be detected in people who continue to experience symptoms such as fatigue or arthritis after completing antibiotic therapy.  |
| Sanfilippo B: Promising new therapy for devastating genetic disorder Posted: 12 Feb 2014 10:28 AM PST A promising new therapy has -- for the first time -- reduced damage to the brain that can be caused by Sanfilippo B (MPS IIIB), a rare and devastating genetic disease.  |
| Surgical implants: Implant stiffness is a major cause of foreign body reaction Posted: 12 Feb 2014 10:28 AM PST Surgical implants are widely used in modern medicine but their effectiveness is often compromised by how our bodies react to them. Now, scientists have discovered that implant stiffness is a major cause of this so-called foreign body reaction.  |
| Long-term effects of childhood obesity on late-life health revealed by study Posted: 12 Feb 2014 10:26 AM PST "It may be that childhood obesity changes the way the whole metabolism is working – and changes it during a critical developmental time frame," says lead investigator or a new study.  |
| Posted: 12 Feb 2014 08:28 AM PST Seven out of 10 adolescents with mental health problems also suffer from chronic physical pain. Depressed girls suffer the most.  |
| Exercise targets cellular powerhouses to improve heart function Posted: 12 Feb 2014 08:27 AM PST Whether lifting weights in a gym or just walking around the block, exercise has many benefits, such as helping people lose weight and build stronger muscles. Some studies suggest that it may reduce the risk of developing cancer and other diseases. Researchers now report that moderate, long-term physical activity appears to improve cardiovascular health in mice by targeting the heart cells' powerhouses -- the mitochondria.  |
